Birds and bats using buildings as a place of breeding or shelter

Abstract:Birds and bats using buildings as a place of breeding or shelter.The presence of birds and bats was analysed in buildings intended for thermal refurbishment. Study material was collected in the years 2012-2016 in 336 buildings from 11 voivodships. For detailed analyses concerning birds, data from three voivodships were selected: kujawsko-pomorskie, łódzkie and mazowieckie. To determine differences in the location of bat roosts, buildings from all voivodships were compared. Bird nesting places and daytime bat roosts were divided into 22 locations. Regional differences in the occupation of buildings were analysed. For comparison, the analysed buildings were divided into churches, tenements, public buildings, and residential blocks. Buildings used by birds were also compared with respect to the degree of urbanization of their surroundings. Species-specific differences in their preference for occupying buildings of different types were analysed in birds. Birds were found in 78.9% of buildings and bats – in 8.9% of buildings. 2,250 bird nests in 265 buildings and over 1,000 bats in 30 buildings were inventoried. The bird species most often found in buildings were: the swift Apus apus (40.5%), house sparrow Passer domesticus (31.7%) and jackdaw Corvus monedula (9.9%). Bat species found in buildings included: the common noctule Nyctalus noctula, serotine bat Eptesicus serotinus, lesser horseshoe bat Rhinolophus hipposideros, pipistrelles Pipistrellus and long-eared bats Plecotus. The house sparrow most often inhabited buildings in kujawsko-pomorskie voivodship and the swift most often inhabited buildings in mazowieckie and łódzkie voivodships. Birds in kujawsko-pomorskie voivodship most often built their nests under roofs and birds from mazowieckie and łódzkie voivodships in flat roof spaces. A total of 31 bat roosts were located in 30 buildings in five different locations. Bats most often occupied flat roof spaces and attics and least often occupied crevices behind the gutter.Key words:birds and bats in buildings, nesting and roosting places
